Every key shop flow now works via plain HTML forms when JS is
unavailable. LiveView progressively enhances when JS connects.
- PDP: form wraps variant/qty/add-to-cart with action="/cart/add"
- Cart page: qty +/- and remove use form POST fallbacks
- Cart/search header icons are now links with phx-click enhancement
- Collection sort form has GET action + noscript submit button
- New /search page with form-based search for no-JS users
- CartController gains add/remove/update_item POST actions
- CartHook gains update_quantity_form and remove_item_form handlers
- Fix flaky analytics tests caused by event table pollution

Canonical: all shop pages now assign og_url (reusing the existing og:url
assign), which the layout renders as <link rel="canonical">. Collection
pages strip the sort param so ?sort=price_asc doesn't create a duplicate
canonical.
robots.txt: dynamic controller disallows /admin/, /api/, /users/,
/webhooks/, /checkout/. Removed robots.txt from static_paths so it
goes through the router instead of Plug.Static.
sitemap.xml: auto-generated from all visible products + categories +
static pages, served as application/xml. 8 tests.
Also updates PROGRESS.md: marks tasks 55, 58, 59, 61, 62 as done.

Product pages: first 155 chars of description, stripped of HTML, truncated on word boundary.
Collections: contextual description based on collection type.
Content pages (about, delivery, privacy, terms): from hero_description text.
Contact: static description.
Home falls through to site_description from settings (already in layout).
